why in SimpleMPL.cpp file, use bool hor = gtl::delta(pRect, gtl::HORIZONTAL) >= gtl::delta(pRect, gtl::VERTICAL) to as the split condition?

I am trying to build OpenMPL project. However some errors happens with the boost library

How can I fix the problem?

I have tried to change the boost version from 1.55 to 1.72 and try to install boost in other ways. I have also tried to change the installation path. But these still cannot work.

When I am doing a layout decomposition which is from the small dataset, I can't get the result if I set the use_stitch command, it seems to stuck somewhere or how long does this work takes? While I turn off the use_stitch command, I can get the result soon...Hoping that u can help me with that ：）

1. Boost version required

Boost version should be limited up to (1.7.2) since Boost.Geometry in Boost 1.73 deprecates support for C++03 and will require C++14 from Boost 1.75 onwards. I've tried to use Boost 1.77 and compile Boost 1.77 with cxx-std14, modify the CMAKE_CXX_STANDARD=14, But some other compatiable problems ocurred. Then I get the version of boost back to 1.72.

2. gcc - language gfortran needs to be enable since OpenBLAS is required here.'
3. <SimpleMPL.cpp> line 2167 needs to be annotated IF GUROBI is not installed!!!

when "[ 100%] Linking CXX executable OpenMPL",it shows "在SimpleMPL.cpp:中，对boost::timer::format...未定义的引用"
the version of the boost and the gcc that I had was not suitable，so I choose the version that the author recommends，it works
